MACHINE FOR OPERATING UPON THE HEEL ENDS OF BOOTS AND SHOES.

Application filed February 17, 1927, Serial No. 169,079, and in Great Britain March 1, 1928.

This invention has reference to improvements in or relating to machines for operating upon the heel ends of shoe soles (shoes herein including boots also).

Wood heels of shoes are usually provided with a concave upper face and it is customary to trim the heel end of shoe soles so as to produce a more or less convex tongue that is narrower than the sole and which tongue will be received within the concave part of the heel when the latter is applied to the shoe. In order to position the heel correctly in the direction lengthwise of the shoe, it is customary to form the sole with a sort of shoulder on its opposite margins against which shoulders the front or breast face of the heel is engaged at its upper edge.

The main object of this invention is the provision of a heel seat fitting machine whereby the formation of the tongue and shoulders is expedited and whereby the various operations may be performed with great precision. Further, the machine is of quite simple construction and certain adjustments of parts found necessary for different sorts of heels can readily be effected.

In this improved machine the heel end of the shoe sole is deformed by a plunger pressing or bulging the central part of the said heel and through the approximately U-shaped opening in a form-plate, a skiving knife being arranged for movement so that it divides said end for a desired distance by, as it were, splitting off the projecting or bulged through portion of the sole so that if the sole were at once removed from the machine it would have a convex tongue and an approximately U- shaped portion surrounding said tongue which latter is connected by its legs to the sole. It is intended, however, to sever the said legs prior to removal of the sole so that the formation of the heel seat and the severing of the marginal portion of the sole will be effected without disturbing the sole in the machine. It is by severing the legs of the U-shaped marginal portion (so that this latter is completely detached from the sole) that the shoulders on the opposite margins of the sole are produced and according to the angle at which the cuts are made to the plane of the sole, the said shoulders will be either perpendicular to the said plane or they will be more or less undercut. The undercut shoulders are desirable when the front or breast face of the heel at its upper edge projects forwardly. Further, some heels have their front or breast face concave (viewed from the top) and for these heels the said shoulders require to be cut at an angle less than a right angle to the longitudinal median line of the shoe sole. The facility whereby the aforesaid severing of the marginal portion (i. e., cutting through both the legs of the U-shaped marginal portion) may be effected by my improved machine is one of the outstanding advantages of this invention.

An important feature of this invention is a heel seat fitting machine in which the severing of the marginal portion of the shoe sole is effected by cutters that are arranged for movement towards each other, the force applied by one cutter being thus balanced by that applied by the other.

A further important feature of my invention is a heel seat fitting machine in which severing cutters are arranged for movement in the plane of the sole and in the direction transverse to the longitudinal median line of the sole and also in relatively opposite directions.

Another important feature of this invention is a heel seat fitting machine having in combination means to hold the heel end of a shoe sole, a skiving knife to split said heel end, and a pair of severing cutters adapted for movement transversely to the direction of movement of the skiving knife and in relatively opposite directions.

Still further important features of this invention is the provision of severing cutters adapted for movement towards each other and which cutters are arranged (a) for turning about a line or point located in the plane of the skiving cutter 0r b) a point located at the intersection of the longitudinal median line of the sole with the heel. breast line thereof.

The foregoing and other objects and features of this invention will now be described with reference to a preferred constructional form of machine incorporating these but I wish it to be understood that I do not limit the scope of this invention thereto.

In said' drawings I have by way of example illustrated my improved machine as I propose to construct it for fitting theheel seats of soles that are already attached at the forepart and at the waist to a shoe but with slight variation the machine may be conready attached as aforesaid to the shoe provided adequate means for positioning the shoe are provided in that the heel seat fitting can be effected with greater accuracy for the particular shoe to which the heel is to be attached.

Referring to said drawings, Fig. 1 is a side elevation showing merely the form plate and plunger and means for guiding a shoe. Fig. 2 is a side elevation showing the machine in eater detail. Fig. 3 is a front view and ig. 4 a top plan.

In said drawings the reference numeral 5 indicates a standard on which is mounted a head 6 to carry the working parts. At a suitable part at the front of and projecting forwardly from the head 6 I provide a formplate 8 that has an approximately U-shaped opening. Adapted for movement in a direction perpendicular to said form plate I provide a plunger 10 the stem 11 of which is received in a vertical bearing 12. The plunger is normally held raised some distance above the form plate by a sprin 13 and it may be depressed by the operator depressing a treadle lever ('not shown) to which is attached a rod 14 the upper end of which is pivotally attached to the one end of a rocking lever 15, supported on a pivot 16, the other end of which is connected by a link 18 to one end of a second rocking lever 19 supported on a pivot20 the other end of which is formed with a more or less semispherical head 21 that engages against the upper end of the stem 11. An adjustable stop pin 22 is provided on the .lever 15 thatis arranged to engage against a block 23 thereby limiting the downward movement of the plunger. The heel end of the sole is to be placed on top of the form plate 8 and when correctly positioned the operator will depress the treadle rod 14 and thereby, by the connections already described, the plunger 10 will press the central part of said heel through the U-shaped opening in the form plate. This will cause a part of the central portion to be bulged through the form plate so as to project beyond the lower face thereof. Whilst the operator holds the shoe thus deformed, he causes a skiving knife 26, that is adapted for movement in suitable slide bearings from the back towards the front of the machine, to cut or gash into the heel and so as to divide the downwardly projecting part of the solo from the part gripped between the plunger and the form plate. The skiving knife moves in close Contact with the lower face of the form-plate so that the operator may, by adjusting the set screw 22, determine whether the part depending from the lower face is of the full thickness of the I sole or whether it shall be of any less thickand (b) whether a ridge or shoulders will be formed at the sides only or right across the sole when as will be described the severing cutters are operated.

The skiving knife 26 will be moved forward so that its cuttingedge reaches (01' passes slightly beyond) the heel breast line,

owing to the sole being held in deformed condition whilst the skiving knife Was making its out the sole will have been formed with a substantially convex tongue at its heel end and surrounding said tongue will be an approximately U-shaped marginal trimming that still adheres by its legs to the sole at the breast line. Further, if the plunger 10 did not depress the central part of the sole to the full depth of the thickness of the sole, there will be a more or less thin layer of thp sole adhering at the breast line to the so e.

It is not intended, however, to remove the sole until the two legs of the marginal portion (and the thin layer referred to also) have been severed and for this purpose I'provide the following Secured to the front of the head 6 I provide two brackets 30, 31, one on each side of the form-plate and of the plunger. Each bracket is provided with an arcuate slot 32 through which projects a bolt 33 that carries a bearing 34 for a sleeve-like member 35. The bearing 34 is adapted to be clamped by a clamping screw. 37 so as firmly to grip the member 35.

Passing through the member 35 is a spindle 39 which at its outer end is pivotally secured to a lever 42 which is at its rear end connected by a link43 to the machine head and at its front end is provided with a handle 45. Secured to the spindle 39 by its shank 48 is a severing cutter 50 the lower extremity of the cutting edge of which is in the plane (substantially) of the upper face of the skiving knife and the shank 48 engages in a slot in the sleeve member 35 so that the s indle 39 and severing cutter 50 are adapted to e moved in the direction axially of the spindle. By adjusting the position of the sleeve like member 35 about its axis the angular position of the severing cutter may be set so that when the handle lever 42 is actuated the severing cutter 50 will sever the leg on one side of the U-shaped trimming (of course the corresponding cutter 50 on the other side will be instrumental in severing the other leg). If there is adhering a thin layer or flap as described it will be merely necessary to move the severing cutters 50 until they reach the longitudinal median line of the sole when the said flap and the legs of the U-shaped marginal portion will both or all have been severed so as to be completely HHS lit)

detached from the sole. If there is no flap as aforesaid left attached to the sole, on the completion of the severing cuts by the cutters the sole will merely have a shoulder at each side. If however a thin flap was left adhering to the upper face of the sole then, when the cutters 50 have been operated, they will not only form shoulders on each side but a shallow one across the face of the sole also.

1 )Vhether the shoulders will be undercut or not depends upon the adjustment of the parts as already described. It has been pointed out that some heels have a concave breast face (viewed in plan) and therefore it is desirable to cut the shoulders not at right angles to the longitudinal median line of the sole (which would be suitable for heels having a flat breast face) but at some less angle according to the shape of the heels to be attehed to the shoes and for this purpose the operator will slacken back the screw 33 and adjust the bearing along the arcuate slot and again clamp the parts in adjusted position.

In order to ensure accurate positioning of the shoe there are provided two gauges 53, 54, against which the heel end of the shoe is engaged. The former of these engages the heel and so as to determine the position thereof laterally and the other, 54, to determine the position longitudinally of the shoe. The gauge 53 is yieldingly sup-ported so that the workman when he has engaged the heel end of the shoe therein can push this back until the shoe engages against the gauge 54. There is preferably also gauge 56 against which the operator holds the forepart of the shoe and this gauge is carried on a pivot 57 on lugs 58 so that the operator may lift the gauge and swing it out of the way if and when he does not require to use it. All the gauges are adjustable.

For operating the skiving knife 26 by power I provide a driving shaft 60 and pulley 61 deriving power from a suitable source, also a friction clutch and other usual fitments.

The operator by depressing the forward end of a lever 63 releases the snail 65 whereupon the eccentric 67 acting through its strap 68 and rod 69 actuates a rocking lever 70 supported on the stud 71 and connected adjustably at its upper end by a link 73 to a slide rod or frame 7 5 to which the skiving knife 26 is secured.

Further, by tilting the severing cutters so that their. cutting edges are at an acute angle to the plane of the sole and by first cutting (by a leather splitting machine) a thin apron or breast flap on the tread face of the sole, the heel seat will be prepared suitable for a full Louis heel, it being understood that when the severing cutters produce mere shoulders as firstly herein described the heel seat is suitable for semi-Louis heels.
